accessing variable from inside a class

Hi,

How do i access a variable from inside a class? ex. I want to use
$template_dir inside Template.


$template_dir = 'templates/';

class templateParser {
var $output;

function templateParser($templateFile='default_template.htm')
{
(file_exists($template_dir.$templateFile)) ?
$this->output=file_get_contents($template_dir.$templateFile)
:
die('Error:Template file '.$template_dir.$templateFile.' not found');
}

}

I run Fedora 10, apache 2.2.11 and php 5.2.9.
I get an error saying that $template_dir is undefined.

Regards
Lars Nielsen

Add the following statement:
global $template_dir;

Well you have to access it as a global by either declaring it global in
the method (global $template_dir;) or by the superglobal
$GLOBALS['template_dir']. However this is probably not the preferred
way to do it.

I would either define it as a constant define('TEMPLATE_DIR',
'templates/') or you could pass $template_dir into the class constructor
and have it set as a class var, but I prefer the constant.

Re: accessing variable from inside a class

I cant get it to work. I will use a configuration class instead.

function templateParser($templateFile='default_template.htm')
{
$c = new config();
(file_exists($c->template_dir.$templateFile)) ?
$this->output=file_get_contents($c->template_dir.$templateFi le)
:
die('Error:Template file '.$template_dir.$templateFile.' not found');
}
